Subject: [PATCH 3/4] pwm: pca9685: initialize all LED registers during probe
Date: Wed, 26 Feb 2020 14:52:28 +0100	[thread overview]
Message-ID: <20200226135229.24929-3-matthias.schiffer@ew.tq-group.com> (raw)
In-Reply-To: <20200226135229.24929-1-matthias.schiffer@ew.tq-group.com>

Initialize all ON delays to 0 during probe, rather than doing it in
pca9685_pwm_enable.
